How to check the webcam?

Question

I am running Ubuntu 8.04, and recently I received the following error while visiting a website:

Please return to www.site.com with a computer running Windows 98, 2000, Me, NT, or XP.

• How does a website know which OS I'm running? Is it only through javascript or is there information about the OS in the request headers?

• Is there a way around this check or “pretend” to use Windows so that I can access the website even if I run an unsupported OS?
